[QUOTE="Tourmax, post: 206406, member: 5304"] So now I had probably the rattiest FJ I had ever seen in my garage. Time to do something with it. First off, chucked a battery in it. now it at least starts on its own. Out comes the oil and filter. Yuck. No missing the fact its been in there for a very long time. Next up, off came the carbs. Stripped ’em down to nothing and dropped in the ultrasonic. The crap that floated up to the surface was enough to make me gag. But now they were clean, inside and out. Put them back together, did some quick idle mix adjustments and it was ticking over beautifully. Then I made a new vinyl seat cover since the old one was ripped in several places. While I was at it, I stripped off the rear top rack mount someone had installed: [ATTACH type="full" alt="DE4CCE8B-AD01-4E54-9889-3C268564A916.jpeg"]39984[/ATTACH] Bloody buggers punched holes right through the tail fairingand bolted it down. This cracked the tail fairing, in addition to the three big holes. A quick bit of muffler cement fixes up a hole in the LH muffler and a quick shot of high temp black hides it. A PO had installed mufflers from a later year on it. This put the mounts in the wrong place and they had just cut a piece of steel pipe to make up the difference between where the mid pipe stopped and the mufflers started. Not such a big deal except they used regular muffler clamps on them, which dented the crap out of the mid pipe. Oh well, at least it worked. a little more fettling and I drove it for the rest of that season: [ATTACH type="full" alt="DA71E4F6-7BC8-471C-A50A-CE0C3853D7F1.jpeg"]40008[/ATTACH] Worked great, although you could tell it needed some attention, both cosmetically and mechanically. So that winter, parts started to flow. First was a set of new/used side covers.
